KSI and Logan Paul will take to the ring tomorrow at the Manchester Arena in what is expected to be the biggest event in YouTube’s history.
But the showdown has been heavily criticised by professional fighters.
British heavyweight Tyson Fury called the British and American vloggers a “pair of b****rds” today.
While UFC legend Michael Bisping said the whole fight was an “insulting mockery”.
And now Steve Bunce has had his say on the bout – but fans of the YouTube stars will not be happy.
Speaking to BBC Radio 5 Live, the boxing pundit says: “It is a joke, it is a shambles, it is ridiculous.
“It will be a very poor bout technically but they are both evenly matched.
“They are both inept – they are both unable to basically stand up.
“And I know people who were in the gym watching them when the cameras were’t there in the last 10 days or so.
“That means bizarrely it will be become a donkey derby, two people that are evenly matched.
“They are not boxers and what’s more they’re not even poor imitations of boxers.
“But tomorrow night, if they get half the thousands they’re expecting, they will become the two highest paid boxers in the world this year.
“I can’t believe I’m saying this but sadly it’s true. They could be walking away with 30 or 40 million quid each!”
The host then asks Bunce to give his prediction for the fight.

And he quickly replies: “Oh KSI all the way for God’s sake!
“Logan Paul cannot stand up! It’s KSI!”
At the weigh-in earlier today, KSI pulled an unbelievable stunt on opponent Logan.
While his younger brother Deji was rinsed for what he did at the event.
